Acer Television AT2703 Flipping through inputs automatically

For the last two days, my television has been skipping through the various video inputs automatically. The delay between switching is anywhere from 10 seconds to immediate. I've checked the input button on the tv and the remote to see if it was stuck. It also has ``rebooted`` itself a few times (tv is on with a green power light, then the power light goes completely off as if there is no power to the tv, then turns red to show it`s off, then green again, and the tv comes back on) Is this a damaged board that can be replaced? I have had the tv for 6 years now and have had no other trouble with it.

Re: Acer Television AT2703 Flipping through inputs...

Seems like your set now has a poltergeist in it after all these years. If set turns on an doff by itself and works erratically there could be a power supply issue since it supplies the juice for the various areas to do their thing. If PS is messing up, so will other sections of your set.

well the problem sounds like it could be the IR sensor on the tv or somthing in that circut that is failing or the EPROM chip that controls : Vol up/down , Channel up/down , Power on/off ,Menu , Input selection , ect... is failing, thus this will trigger the protection circut to shut the tv down. this kind of a problem only gets worse and can dammage other components if not repaired soon so it will need testing to determine the exact cause

it costs $2.50 to fix its 2 capacitors in the motherboard need to change them very easy i just fixed mine took me an hour all together and less then 3 bucks .if you open the tv look in the middle motherboard and you will see witch capacitors are blown because the top of them is raised up change them and ure done,all the capacitors have a cross scored in the top ,so they dont blowup ,so if you see 1 raised just a little bit its fried change it while ure in there , they wanted $400 to $500 to fix lmao now .

The TV has developed a fault where the start up procedure cannot be carried out & therefore the TV switches itself back off. You would need to remove the back of the TV & check if there are voltages going to your backlights (24v), are there all the other voltage rails present at start up eg 15v, 5v etc. Check the power supply to see if any of the capacitors are showing signs of stress such as a bulging on the top. If you do not have a multi meter to check voltages or feel comfortable to do this, then it would be best to contact a repair service centre.

It would be helpful to know what cable your trying to connect, component, S-VIDEO, HDMI, etc. Also the make & model of the combo unit & Toshiba TV. However the basic process is usually the same for most hardware. Make sure the connection to combo unit is "video/audio out" not in and make sure the input for the TV says IN not OUT. Then you need to set the TV to the correct input channel. And then make sure the combo unit is using the correct output... usually this is automatic for component cables but not always.

If you are unable to view video on your television set, the issue may
be that the TV's video input selection does not match.

The TV input source must match how the equipment for example DVD is connected to the TV. Every TV is different in the way that
the ports are configured on the back of the TV and the menus are
presented on the TV screen; however, there are some basic similarities
between them.

To correct the issue, use the TV's remote control
and change the video input selection. Many newer TVs have an
auto-detection system and will automatically detect that something is
connected to the various ports on the back of the television. However,
some TVs have to be configured manually.
Some common names of the button on the TV remote are:

Video Source

Video Input

TV/VID

Locate the video input menu for their specific TV. Below is an example of the video input menu of a TV.

This example indicates check boxes next to the items that the TV is detecting. Be advised that this menu must match the location on the back of TV where video components are connected.You may also check if all cables are properly connected.

What you have done is change the input source. It will toggle through various modes like component, HDMI1, HDMI2, S-video etc., You should take a look behind the tv and see which input you have connected it into(usually HDMI 1 or HDMI2) then keep pressing the input button till it toggles back to that particular input.

is the channel flipping always happening at set intervals? Or, just randomly? Try replacing the batteries in the remote. If that doesn't work, start looking for other sources of IR(infrared). In some rare cases, direct sunlight on the TV will get it to do strange things.

This function will block out the picture and sound of the selected channel or video input.
It can also be used to keep the TV from being viewed for a scheduled time period that you set.
The code to enter the Locks feature is a four digit secret code number. The factory preset code is 0000.
Use the number buttons to select access code.

Use CURSOR G or H to highlight function and then press the SELECT button.
To change the access code number, select Change Access Code. Enter a new four digit key number you prefer.
Select CHANGE ACCESS CODE to change factory preset code (0000) to your preference.
When ENGAGE LOCK is selected, SET CHANNEL LOCK, SET INPUT LOCK, and SET FRONT PANEL LOCK can be set individually.
When SET CHANNEL LOCK is turned on, the picture and sound for the chosen channel will be blocked out.
When SET INPUT LOCK is turned on, the picture and sound for all video inputs and the picture and sound for channels 3, 4 will be
blocked out.
When FRONT PANEL LOCK is turned on, all buttons on the Front Panel will be deactivated, except the Power button.
When TV TIME LOCK is turned on (r TIME LOCK) you can set the BEGIN and END times (CURSOR E) and the TV
cannot be viewed during that time period (Set clock first). Use CURSOR G or H to highlight ONCE (TV will time out one time
only), DAILY (TV will time out every day), WEEKLY - SUN~WEEKLY - MON (TV will time out one time a week) or OFF (to disable
this function).
When MOVIE RATINGS is selected, you can block various types of movies and video tapes based on motion picture ratings. Picturein-
Picture will also be blocked automatically (see page 45).
When TV RATINGS is selected, various types of television programming based on a parental guide ratings will be blocked.
Picture-in-Picture will also be blocked automatically
If you forget your secret code, use the factory code 7777 to erase your key number. This will reset the secret code number back to the
factory preset 0000.
Press EXIT to quit the menu.

Press the TV/Video button on the remote. If it skips those inputs its possible the inputs are skipped in the set up menu you need to go in the menu and set up the inputs...It may be becuase there is no signal to those inputs as well.
